Umax S900 CD Rom problems...

Umax S900 CD Rom problems...

[Velasquez, Carlos]

Hello,

Has anyone successfully installed  Linux on a Umax S900 Mac clone? If so,
can you share your stories with me? I am having problems installing Linux on
my Umax S900 (225 Mhz ppc with 162Meg ram, ixMicro Twin Turbo 8Meg video
card.) Apparently, when I try to do a CD install, the installer doesn't
recognize the CD Rom device. I believe I have a Matshita CD rom drive
installed as an internal SCSI device (bus 0, Id 4).

Also, has anyone had any success installing Linux from a Jazz drive? Any
help will be greatly appreciated!

Carlos

I gave up. ;)  First attempt, the installer did not recognize the Twin Turbo.
Someone
on this list offered a fixed installer.  Then, the machine lost track of the
CD, so the
installer displayed o.k. but could not see anything to install. ;)  Then the
whole
SCSI went invisible - no CD, no floppy, no Zip.  Soooo, sent it to the shop,
where
they replaced the motherboard (where the SCSI chip was mounted).  Now the
installer
won't write (correctly) to the internal hard drives.  Seems the E100 chip sorta
refuses
to let the two 2-gig disks be anything but RAID, no matter how I initialize
them.
And then too, it's a twin processor SMP, and THAT won't run anything but the
Umax-supplied demos (MacOS 7.6) and then for a maximum of 30 minutes.

I'm parting it out ;).

What version of LinuxPPC are you trying to install? I've gotten R4.0 and
pre-R5 to install on my dual 180MHz S900. Though both installed over the
net, but both were able to see both SCSI busses and both my Matsushita CD
and Panasonic CD-R. I've also gotten it to run MacOS 8.0 and 8.1. Haven't
bothered with 8.5 or 8.6 yet. I am currently having my latest kernel
2.2.6-15apmac to use my Matsushita CD though. I don't use it very often,
so I don't know if any earlier 2.2.x kernels also gave trouble. My CD-R
works just fine though.

Umax S900 CD Rom problems...

[Packer, Dave]

Carlos - 

I have a UMAX S900/200 with the Matsashita drive.  I've been able to install
without any problems.  What
OS are you running? I'm running 8.5.1.  I've installed 4.1 and now am
running Pre-R5, except for some very small FBDev problems I'm perfectly
satisfied with what I have.  Are you installing with BootX? make sure you
de-select no-video-driver and you can pass the arg of video='tt128fb' to the
kernel.  

Other Notes:

Don't run the installer from a HFS+ partition
I've had the best success by dragging the RedHat onto an non-HFS+ partition
and installing from there

If you are shooting for Pre-R5: I know that about a week ago I thought I
might try re-installing and had some problems with the recent
redhat.ramdisk.gz where it couldn't recognize any of my drives.  That might
be where your problem is.  Can't help you there though probably have to wait
until R5 comes out sometime in the next week or so.

Dave-

RE: Umax S900 CD Rom problems...

[Velasquez, Carlos]

Dave,

Thanks for the help. I am running Mac OS 8.1 and using the BootX utility.
Out of curiousity, is there a difference whether I run 8.1 or 8.5? (If so, I
will load upgrade to 8.5, I have the disk but wasn't sure if it was fully
compatible with clones.)

I will try passing the arg video='tt128fb'. Your suspicions were correct, I
am trying to go with the Pre-R5 version. I will try 4.1 then try moving up
to Pre-R5 instead. Someone else also suggested that I try YellowDog Linux's
ramdisk.gz file (it is supposed to have an improvement in the installer for
the CD method.)

Will keep y'all posted!

Carlos
